  • @mutelatedLEMON

    This all happens when the ejection port is open. A very short time radius to do all this.

    I hope you understood :)

    I also have a video about it ;)

  • @mutelatedLEMON

    on the magazine follower you have a piece on the left side that extends but still is flush with the mag body. On the end of the slide catch.. (the side you push your thumb on)

    There is a piece that goes in the frame of the frame. So after the last round, the extended piece of the mag comes against the inward extension of the slide catch. The spring of the mag pushes it up. Therefor the slide catch is pushed up and the slide catch engages in the slot of the slide. This all happe

  • I'm confused as to the 7 rounds v. the 8 rounds. Is that "one better"? Or is the 7 round mag one less?

  • its the slide stop that confusis me

  • 8 round mag? what? dont the 1911 hold only seven? what you cant do with seven rounds you cant do anyway?

  • @tellyman6688500 8 round mags are very common. The extend down a little and have a plastic base on them. I only own one 7 round magazine.

  • @DarwinTe i see. didnt think an original 1911 would have 8 rounds in the magazine.

  • @tellyman6688500 No, they didn't. The original magazine were 7 rounds and the bottom was flush with the bottom of the frame. I think the extended magazines were designed to make it easier to change magazines quickly, like in competitions, and the extra round was just a bonus. I may be wrong, but that is my opinion of it.

  • @DarwinTe that could be for competitions yes. with eight rounds they dont need to cock the gun again after a new mag was inserted too.

  • @DarwinTe Oh. But I didn't think an original 1911 was supposed to have 8 round magazines. (lets see how many times he answers this same inane question - must have patience of a monk)

  • Why the fuck does the magazine drop after every shot?

  • American Pistol Design And Performance by L.R. Wallack 

  • God I really could watch this all day long! STI FTW!!

  • I can't belive how simple guns are.I think I could take this gun apart and see how it works I can make one myself.

  • @FOnline2238Advisor it's more complex than you might think. you have to melt and weld all those frame peices. make all those componets to the nth degree and make sure it can actually fire. but, that said if you have a good sense on mechincal engineering and practical with metal, it shouldn't be to hard

  • In reality, the barrel and slide move toward the rear as the bullet moves to the front.

  • You are right. It's a flaw in the animation. 

  • @DarwinTe, Thanks for responding.

    I'd be curious to know what your estimation of the length of motion of the barrel and slide would be, while the bullet is transiting the bore?

  • @InfidelArmee

    I have no idea. Not very much. The bullet is going over 800 feet per second. How long could it take to go 5 inches?

    I did the math and If my math is right it takes the bullet about 1/10,000 of a second. (0.0001) to clear the barrel.

    I DO know the barrel and slide move as a unit for a small distance, then the link lowers the back of the barrel and unlinks it from the slide. This gives the case time to expand and contract before being extracted.

  • @DarwinTe, I don't think it's a question of time. It can be expressed as a momentum equation.

    If the bullet and charge weigh 250gr., and the barrel and assembled slide weigh 7000gr./1lb., the barrel and slide will move about .180" as the bullet moves 5", if the forces acting on them are equal.

    Since the .45ACP is a straight wall cartridge, the forces are equal, so that the distances moved are equal to the ratio of their respective weights.

  • @InfidelArmee

    Thank you very much for your explanation.

    Us simple folk think in simple terms. lol

    I didn't think of it the way that you explained.

  • @DarwinTe, The reason I asked, is because I've lately realized that the dynamics of recoil are not very well understood. One of my cousins who was a schoolteacher, and two of my brothers in law, who are automotive mechanics, all shooting enthusiasts, think that the forces acting on the gun are somehow equalized in such a way that the gun doesn't move until the bullet exits the bore.

    A YouTube video called, "Shotgun in UltraSlo Motion", shows it in High Speed. My cousin says the guy's flinching.

  • @InfidelArmee Do you think that the angle shift of the barrel has a negligible effect on bullet direction? If it's consistent, I think the gun is sighted accordingly. Do you think change in ammunition types would cause inaccuracy? (such as a lighter hollow point or heavier tungsten-cored armor piercing)

  • @OvoJeGovno, In the 1911, the angle of the barrel in relation to the grip frame doesn't change much before the bullet leaves the bore. The preliminary motion of the slide is absorbing the thrust pretty much straight back.

    In a standing breech type arm, the rotational moment due to the thrust not being aligned with the center of mass, like a revolver, means that the greater the projectile weight, the greater the rotation during the bullets translation will be, regardless of bullet material.

  • @InfidelArmee Actually, no.  Browning designed the M1911 so the slide/breach break did not occur until the round had left the barrel. This was done to reduce loading on the Link IIRC.

  • @InfidelArmee actually there are videos that let you see the bullet leaving the muzzle in very slow motion and in them you can see the bullet completely exits the muzzle before the slide starts moving

  • @heartline12, There may be animations like that, but in real life, the barrel and slide begin moving rearward the moment gas starts moving forward from the primer. Physical Science is interesting. Especially the Laws of Motion.

  • @InfidelArmee the slide can be moving rewards as the bullet is leaving the barrel in fact with most ammunition it does that why theres locking lugs on the 1911 and why match grade barrels are made. however i have seen a slow motion video of a most likely undercharged round where you can see the bullet leaving the chamber before the slide moved. i can try finding it for you

  • @InfidelArmee The problem is that the second law of motion goes both ways.

    The spring tension and the slide mass counter the recoil operation. If you see a slow-mo video of the 1911 being fired, the bullet will leave the barrel before noticeable movement occurs. Of course that there is movement, but it's really hard to see.

  • @bf2lover42, There is approximately .182" of motion of the barrel and slide, relative to the grip frame, before the bullet leaves the bore. Assuming the machine is a 1911A1 launching 230gr. bullets. There is better than 3000lbs. of thrust against the bullet base and the breechface of the slide, at average pressure. The slide mass and spring tension don't represent significant resistance to that much thrust. Their motions relative to one another, are a proportionality equation.

  • Actually the slide will begin to move back as soon as the bullet begins to move. It is a ratio of the weight of the bullet vs the weight of the slide and force of the hammer spring.

  • I remember seeing this animation long ago when i didn't know what STI was.

  • lol, this 1911 has a spring guide, so stupid

  • i just fell in love with that gun. looking for a bb version now which i can make to a nice old 1911 with wooden handgrips...

  • Comment removed

  • this gun was originally designed in 1908 and then after being pimped the fuck out it was adopted as the standard US military sidearm IN 1911 hence the name of the pistol. its a single action semi automatic pistol meaning that when you gently squeeze the shit out the trigger the hammer falls causing the firearm to discharge, using part of the energy generated by the expanding gases to force the slide back to its most rearward position, then returning to battery chambering another round. repeat.

  • @76239mmboi: hence the term "semi-auto"

  • for the 1911A1 should i add a comp. on it or leave it stock or maybe a silencer

  • what exactly do compensators do

  • @cheezyweezz Exactly that. They compensate. They direct some of the gases upward which compensates for the upward travel of the gun's recoil, therefore making the upward travel of the muzzle less severe in order to quickly get back on target.

  • Comment removed

  • the 1911 is a american design that was used in ww1 when the french invaded germany

  • It was actually produced in 1908. Then it was tested and improved and finally adopted as a US Army side arm in 1911.

  • @OlUncleJoe hence it bieng called the 1911 yh

  • @OlUncleJoe it was produced in 190 and was tested in 1907 and in 1911 the US army adopted it then in 1913 the navy adopted it

  • no. it's called that way  cause it started gettin manufactured in 1911...

  • lol.....

  • So how was the M1911a1 used by troops in WW2?

  • @disturbedone5009 in ww2 they used old fashioned 1911's the 1911a1 started being used in vietnam till present day

  • No the M1911a1 was used in WW2. Now they use the Beretta M9.

  • @disturbedone5009 i know what the fuck im talkin about look it up wiki it stupid ass 1911a1 used in VIETNAM

  • Yeah it was used from WW2 until it was replaced by the M9.

  • @DARIUSX3

    the 1911a1 started its use in world war 2 as the standard issue sidearm.

  • The berretta 92 came in the picture well after vietnam, replacing the 1911 in the decade after vietnam had ended.

  • I know that's what I'm saying.

  • @ Username7260

    did you fail social studies class?

  • No he failed history

  • You are a failure..

  • your an idiot.

  • This is a terorrist or new world order weapon 911 lol

  • It's a miracle you make it through the day without choking on your own spit.

  • the 1911 is called that because of the YEAR it was manufactured...... I have one from 1943 (US&S) and it works great!!

  • whats disconnecting the trigger from the sear?

  • The sear disconnect. It's the pin that goes ly when the slide is into the slide only when the slide is completely forward and the chamber is sealed. Watch LimaLife's vid on the sear disconnect Safety or not?

  • victory01, The problem people have is when one carries the 1911 the way it should be carried. Cocked and locked. That means one in the pipe with the safety on. I don't see a problem with it myself. It is very fast and if properly trained is a good way to carry. Carrying the 1911 with an empty pipe is very safe but not effective and I recommend it to those who are not willing to go to the range at least once a week. Want to carry cocked and locked. get a parking spot at the range.

  • in israel we are trained to cock the gun as were drawing it, because we dont have safety on standard issue guns in the army, we generally dont carry a bullet 'in the pipe' as you say. your right though, if you have a safety, who gives a rats ass?

  • since it's single action. if you initially load the gun while it is not cocked and then pull the trigger what will happen?

  • Nothing.

  • Thanks for the response. I never understood why people are so nervous about carrying a single action because they choose to have the hammer cocked. Just leave it at rest with no worries. I never got it....

  • Glad to help. Took me a while to figure it out, too. It's double actions that scare me. lol.

  • i'm the opposite , and i have no logical explanation for it lol

  • I carry a 1911 for duty and personal carry. My boss hates single action and believes that the double action gives you more time to make sure that you do want to shoot. I believe however, once you take the safty off, you mind is made up.

  • @RandomPoolGuy84

    IMO the advantage of double action is double strike capability whereas the advantage of the single action is a cleaner trigger pull. Depends on what you like. Doesn't really matter what you choose as long as you like it and shoot well with your pick.

  • @RandomPoolGuy84 Your boss is crazy. That kind of thinking can get him killed.

  • @alaskanhybrid He and I are at odds on a lot of tactical situations. He wanted us to use rubber slugs in our shotguns instead of 00 BS. He said, "Have you ever been shot with a rubber bullet? It gets the point across." I responded, "Yeah, but buckshot doesn't give someone the chance to come back with a grudge. We're a security company, not the DPS. If someone is trying to kill us, we have nothing to gain by keeping him alive." Fortunately he changed his mind.

  • @RandomPoolGuy84 hell yeah brother, keep the carry alive.

  • how does that gas blowback works then?

  • i uses the recoil force to push back the slide. the explosion(burning of gunpowder) is underestimated, it has some serious power.

    that being said you cannot make the slide too heavy otherwise it will not cycle properly.

    i am a Glock enthusiast(not fanboy) personally, but i have been to the site where the original flash video was added. very cool.

  • ah i see:D

    and yes glocks rock

  • This has to be one of the stupidest most contradictory comments ever. You say that the barrel is plugged, then write about how it works with no bullet to create opposite force. Why do you think they'd have to plug the barrel if it's only the gas by itself creating force?

  • How stupid. Never, ever let the slide hit the crown on the barrel.

  • I'm hardly a pistol expert and even I knew the 1911 is recoil operated

  • so now that the flame war is over, i wanna say somethin

    A) great animation, very explanitory

    B) *sigh* AK series uses gas blowback, while the Colt uses recoil and a spring system. argument over

  • +1

    It's a recoil-operated weapon. Equal and opposite reaction begins when and where the round exits the muzzle. Not at the bolt face and not by the spent casing.

  • hey did u make that or is it some program?

  • what do you mean by that last part, plz tell me.

  • I'll tell you in a mail message.

  • ok....

  • Yes! Thank God for weapons! How else could we kill all those who don't agree with our religion?

    -scowl-

  • sry. I was just venting religious smoke.

  • are you on drugs, willbutty? cuz that's fucked up.

  • how does it get the recoil system pushing the over part backwards, ive always wondered...

  • The exact same force from the explosion of the powder that drives the bullet forward, drives the casing backwards, wich in turn pushes the slide.

  • Which program is this that you're using? (Please reply.)

  • What about manually loading a gun. not with the magazine, but putting in the bullet where the empty cartridge is ejected? im pretty sure it's possible, but... can any1 do it?

  • On a 1911 with an internal extractor (most of them, this is the original design), doing so can damage the extractor. You should always feed rounds through the magazine. Some 1911s produced nowadays have external extractors which may or may not fair better.

  • are you a cop

  • You will kill the extractor.

  • With a pistol you can get hurt by the slide.

  • yes

    "slide bite"

  • With only 7 rounds you might as well use a revolver with speed-loading clips.

  • Actually I prefer this over all of the revolvers my dad has. And thats not b/c this is my gun haha. It feels much more comfortable to me, and its alot smoother than most of his revolvers.

  • I hate the blow back from revolvers.. you get gun powder all over your face. The 1911 blows it to the right, not backwards into your eyes.

  • plus if your not careful of where you place your hands on a revolver, your hands can get burned by the exhaust gas from the cylinder gap

  • Wow, i dont think that there is any other design of anything mechanical that is still in production after a 100 years. I guess the M1911 design is ageless.

  • wich programme is that

  • its getting boring

  • watch "the BEST colt .45 1911 animation collection ( with labeled parts )"

    it's better....

  • Does the grip safety physically keep the hammer from going forward if not depressed or does it only keep the trigger from being depressed? IE, is only the trigger sear what holds the hammer back? If it breaks, you would get an accidental discharge? I'm asking b/c I have no experience with the 1911, but want to get one. Hammer back carry concerns me. Thanks.

  • The slide safety is what locks the hammer/slide in place, the grip safety prevents the trigger from travel. If the sear slips, the "half cock notch" will stop the hammer from contacting the firing pin.

    Hammer back carry (condition 1) is really quite safe. It is next to impossible for this gun to fire itself without you deactivating the safeties and pulling the trigger. As it happens, the 1911 was designed to be carried cocked and locked.

  • People scream about the beretta and the Glock, but the 1911 is still the choice of the special forces. the first patenting of the gun was actually not in 1911, but rather in 1908. This gun design is 100 years old and still the choice of the best!!!!

  • Keep it simple. The 1911 is simply the best.

  • The Colt 45 was THE BEST hand gun of the 20th century, And it will still remain the best for many century's to come. Unlike those overrated Glocks and Berettas, which will soon be outdated. There will always be a place for the M1911A1. Rather it be for the military, or for the civilians.

  • Wow 100 years it feels like the gun was designed in the 50's or 60's but in 1908 it was way ahead of of its time.

  • What keeps it from being full auto?

  • I suppose it's possible if you had the money or skill to have the trigger assembly completely customized, but why would you need a pistol to be full auto? Why not just buy an UZI or some other submachine gun? Not every gun has to spray bullets...such a waste of ammo. Learn to aim!

  • You missed the point of my question.

  • the trigger has to reset

  • Ok I think i see what you mean. That makes so much more sense thank you.

  • ahh i admit it... i dont know about pistols :)

  • Nice animation! 5/5

  • Actually, in answer to rocker, the M9 is the standard military sidearm. Still, there are disputes cause so many prefer the .45 ACP cartridge, so many special forces units use modified 1911s or 1911 variants like Kimber's as their main sidearm. Most SWAT units use it despite the fact that almost all police forces use nine millimeters, many now going to safe action weapons (glocks).

  • yea our police officers in my town use the glocks

  • LAPD switched from Glock .40's, because they explode. :)

    Glock .40's don't fully support the case, and they have the small chance to kaboom.

  • the barrel should be always fit. It is going backward little bit though.

  • lol this is still standard us sidearm yet it is about 100 years old... lmao this makes me chuckle... must be good tho to say it has lasted that long

  • I can't speak for other branches of the U.S. military but

  • I can't speak for other branches of the U.S. military but I know the Air Force uses the 9mm Beretta now.

  • if its not for the browning locking system, Glocks, HK USPs, SIGs handguns wouldnt have existed :D

  • e a 12

  • this animation thinks he is on a FPS >.> reloading everytime so he doesnt run out of ammo... lol

  • what website did u go to for these animations?

  • It's in the description now

  • Thats awesome...i never ever thought of seeing a gun shot in animation.

  • i love STI

  • I love them because they told California to go pound sand after it passed some stupid gun law - I think it was the microstamping law.

  • hehe. funny

  • Yeah they have that stupid law. Maybe they should do it with all cutlery too so they "feel" even safer.

    I live in the PRK People's Republic of Kalifornia.

  • anyway...gun laws in California are bullshit but...who voted those suckers?is our fault

  • I can't vote yet, but I'll be careful when the time comes.

  • Awesome video !!

  • how do you get these animations

  • Another good example of a Browning type pistol, is a vid for the AAC Black Box. The guy shows slow-mo. And in Slow-mo you can see the hammer drop, the the slide come back ect.

    And correct me it im wrong but, isn't any pistol, that has the tilting barrel a Recoil Action? Like Glock.

  • There barely ARE any pistols, that aren't recoil operated. It only makes sense if an Ammunition is too strong. Desert Eagle being the most popular example.

  • Fixed barrel is blowback right?

  • nope, the slider goes backwards

  • @shazee083

    The slide goes back, but the barrel is still fixed, isn't it?

  • yea

  • well not really the barrel does move slightly still but it is considerd fixed i think

  • i see

  • he used the same animation over and over again lol

  • if browning had access to computers, can you imagine how much more different the 1911 would have been? god, if he had access to computers he'd probably make the first laser pistol, one things for sure, browning was a genius

  • Yes I agree John Browning was a genius but I wouldn't have the 1911 any other way that it is right now...best pistol by far hands down!

  • agreeded, cannot beat classics!

  • word that pistol is like the ak of rifles

  • the recoil of the bullet when fired force's it to draw back. then at that second, the draw back allows the chamber to open at the top and ejects the shell caseing, then the sping in the magazine pushes the next round up into the chamber and close's, and is ready to discharge again.

  • i see, i never thought that the recoil would that be powerful..hehe i've never fired a .45 cal. before, only .38 cal. revolver pistol.

  • All semi autos work that way.

  • i dont get it! what causes the gun to draw back so it can load a fresh round? i mean why does it slide?

  • the part that "draws back" as you put it is actually called the "slide" of the pistol. in this particular example the slide is driven by gas pressure that builds up as a result of the bullet being fired. i think it's called "gas driven blow-back" but i very well may be wrong there :-)

  • so u mean when the gas is released in the barrel it kicks back?

  • Yes. And the recoil springs moves the slide forward again.

  • in effect, yes. the way i understand it, the combustion of the gunpowder produces a gas byproduct (i believe mostly CO2) that travels behind the bullet. the semi-automatic uses those gasses to drive the slide back, thus ejecting the spent cartridge and loading the next one. this is also the "kick" that one feels when firing said weapon

  • Sort of.... The force that drives the bullet out is the same force that causes recoil and the slide to come back. Every action must have an opposite and equal reaction. This is why movies mislead when someone is shot and flies backward. This would in turn mean that that shooter would experience that same force and be thrown back.

    Ar15's and other guns actually work by "gas blow back" and the 1911 is not one of them.

  • the recoil of the bullet when fired force's it to draw back. then at that second, the draw back allows the chamber to open at the top and ejects the shell caseing, then the sping in the magazine pushes the next round up into the chamber and close's, and is ready to discharge again. lol usaully I dont type this much. :)

  • Whoah... I didnt know the barrel moved in relation to the other parts of the gun! Learned something new today

  • That is done so that the pressure can drop. The barrel and slide move together for a short distance. This gives time for the pressure to drop. Then the rear of the barrel drops slightly, releasing the slide from it. The slide continues to move rearward, taking the empty case with it.

    In guns using the blowback system the barrel is stationary, attached to the frame. When used with larger calibers the slide must be much heavier. Hipoint pistols are an example of this.

  • Another reason why rifles are inherently more precise than pistols?
